repetitive stress / carpal tunnel syndrome.
I'm riding Paris-Roubaix this year.
I rode it 2-3 years ago. It is nothing like anything I've ridden before or since. Literally by the final sector I could barely hold my bars. True I was riding with boys and Ian Cleverly who were trying to smash each other. I got to the velodrome and thought I was going to cry because every 1km was 1 to many.
I only wanted to eat savoury food.
I remember I drank a red liquid a feed station and shook it up on the next cobble section and puked up red sick.
The day after I couldn't change gear in my car for the pain in my wrists.
Anyways I'm going again. Its epic. I have to go.
